Abstract: The Karaisalı limestone is a yellowish grey (10 YR 8/2), well indurated, tight and non to poorly beddedbioclastic limestone with well bedded horizons; there is frequent interfingering between the non-and poorly bedded stra-ta. Itis divided in six subfacies: 1) Coral-algal packstone and boundstone; 2) Small benthic foraminiferal-algal packs-tone; 3)Coral-algal wackestone and packstone; 3) Large benthic foraminiferal-algal packstone; 5) Globigerinid-algal packstoneand 6) Globigerinid argillaceous wackestone. All intertongue complexly with one another and are composed of variouscombinations of coralline algae, corals, foraminifera, echinoderms, moluscs, with minor amounts of Hatimeda, bryozoa,worm tubes, matrix and calcite cements. They accumulated on pre-Miocene topographical hiphs and within the adjacentareas as bank and associated deposits.
